RegEx:如何匹配所有大于 954 的数字? [英] RegEx: How can I match all numbers greater than 954?

问题描述

我试过 ^([0-9]\d|\d{4,})$ 但它没有给出正确的结果.

I tried ^([0-9]\d|\d{4,})$ but it does not give the correct result.

推荐答案

我不会为此使用正则表达式，因为您会陷入丑陋的模式链中.

I would not use a regex for this since you will fall in an ugly chains of patterns.

但是，如果仍然必须或想要使用一个，您可以使用这样的正则表达式:

However, if still have to or want to use one, you can use a regex like this:

[1-9]\d{3,}|9[6-9]\d|9[5-9]{2}

工作演示

这个正则表达式背后的想法是:

The idea behind this regex is:

[1-9]\d{3,}   --> This will match 4 or more digit numbers
9[6-9]\d      --> This will match numbers between 960 to 999
9[5-9]{2}     --> This will match numbers between 955 to 999
                  you could write this pattern as `95[5-9]` to cover 
                  numbers from 955 to 959 if you wish (it's up to you)
